When managing a collection, the options on the Collection tab let you manage multiple objects at once. These views by default only shows 10 objects at a time. For 1,000+ objects, this means a lot of screens and a lot of clicking.
But the number of objects that appear on this screen can be configured. Just go to the Collection Solution Pack config page: admin/islandora/solution_pack_config/basic_collection
Under the field “Objects per page during collection management”, just change the number.
